Guys can pitch a tent, well get ready for the reverse tent.
The reverse tent is for when you have to shit , but are trying to hold it, THUS it 'turtles' in and out- which is why it has also been known as a "turtlehead"
Guy 1: " I was pitching a tent last night watching some porn before bed."

Guy 2: "I was pitching a reverse tent at the movies with my girlfriend last night."
